Train yourself to cut off an intrusive thought immediately… Be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act all the rest of your life.
A worker takes the trouble to get hold of the instruments that he requires. He does so not simply to have them and not use them. Nor is there any profit for him in merely possessing the instruments. What he wants is, with their help, to produce the crafted objective for which these are the efficient means. In the same way, fasting, vigils, scriptural meditation, nakedness and total deprivation do not constitute perfection but are the means to perfection. They are not in themselves the end point of a discipline, but an end is attained to through them.
The fear of the Lord is the beginning of our salvation, and its constant guardian. This it is which secures both the beginning of conversion, and the purging away of vices, and the safe retention of virtues...
Till the advent of grace man lives his life and thinks that all is well and prosperous with his soul; but when grace visits him and dwells with him he sees himself quite otherwise, and losing grace again he realizes his unhappy state.
If you will pray for your enemies, peace will come to you; but when you can love your enemies - know that a great measure of the grace of God dwells in you, though I do not say perfect grace as yet, but sufficient for salvation. Whereas if you revile your enemies, it means there is an evil spirit living in you and bringing evil thoughts into your heart, for, in the words of the Lord, out of the heart proceed evil thoughts - or good thoughts.
The brothers said, 'Why is it that the monks are obliged to go around begging for the food and clothes they need, like those who are in the world, although our Lord promised them, saying, ‘Seek ye first the kingdom of God and its righteousness, and that of which ye have need shall be given to you’ (Matt. 6:23)?' The old man said, 'This saying is a proof of the wisdom and grace of God toward those who are in the world, for in the majority of cases, the righteousness of the children of this world consists of alms and compassion; but the children of light are righteous people and monks who, in their persons, and in their bodies, and in their thoughts, serve our Lord. And God has made the monks to have need of the children of this world because of His love, so that they may care for each other, and may pray for each other; that is to say, the children of the world must care for the monks and the monks must pray in love for them. And as the children of the world make the monks associates with them in the corporeal things of the world, the monks must make the children of the world to be associates with them in the things of heaven, for our Lord spoke to the children of the world, saying, ‘Make ye to yourselves friends of this mammon of iniquity so that when they have become perfect they may receive you into their tabernacles which are forever.’ (Luke 14:9)
The belly when filled with all kinds of food gives birth to seeds of wantonness, nor can the mind, when choked with the weight of food, keep the guidance and government of the thoughts. For not only is drunkenness with wine wont to intoxicate the mind, but excess of all kinds of food makes it weak and uncertain, and robs it of all its power of pure and clear contemplation. The cause of the overthrow and wantonness of Sodom was not drunkenness through wine, but fullness of bread. Hear the Lord rebuking Jerusalem through the prophet. 'For how did thy sister Sodom sin, except in that she ate her bread in fullness and abundance?' (Ezek. xvi. 49)
For never is a man forced into sin by another’s fault, unless he have, stowed away in his heart, matter for evil deeds. Nor is a man to be held a victim of sudden deception if at the sight of a woman’s beauty he fall into an abyss of vile lust. Rather is it that diseases of soul, deeply hidden away and lost to view, come then to the surface on the occasion of the sight.
Once two brothers came to a certain old man. It was his custom not to eat every day but when he saw them he received them joyfully and said, 'A fast has its own reward, but he who eats for the sake of love fulfils two commandments: he leaves his own will and he refreshes his brothers.'
The Saints in Heaven through the Holy Spirit behold the glory of God and the beauty of the Lord's Countenance. But in this same Holy Spirit they see our lives too, and our deeds. They know our sorrows and hear our burning prayers. When they were living on earth they learned of the love of God from the Holy Spirit: and he who knows love on earth takes it with him into eternal life in the Kingdom of Heaven, where love grows and becomes perfect. And if love makes one unable to forget a brother here, how much more must the Saints remember and pray for us!
And the old man also said, 'God saith unto thee thus -- if thou lovest Me, O monk, do that which I ask, and do not that which I do not desire. For monks should lead lives wherein they act not in iniquity, and a man should not look upon evil things with his eyes, no hear with his ears things which are alien to the fear of God, nor utter calumnies with his mouth, nor plunder with his hands; but he should give especially to the poor, and he should not be unduly exalted in his mind, and he should not think evil thoughts, neither should he fill his belly. Let him do then all these things with discretion, for by them is a monk known.' The old man also said, 'These things form the life of a monk: good works, and obedience, and training. A man should not lay blame on his neighbor, and he should not utter calumnies, and he should not complain, for it is written, 'The lovers of the Lord hate wickedness.'
How great the evil of pride is, that it deserves to have as its adversary not an angel or other virtues contrary to it but rather God Himself! For it must be noted that it is never said of those who are caught up in the other vices that the Lord resists them, or that the Lord is set against the gluttonous, or fornicators, or the angry, or the avaricious; this is true of the proud alone. For those vices only turn back upon wrongdoers or seem to be committed against those who have a part in them -- that is, against other human beings. This one, however, of its very nature touches God, and therefore it is specially worthy of having God opposed to it.
Keeping the thought of God always present before you, this form of words for your devotions is ever to be put first: O God, make speed to save me; O Lord, make haste to help me. For this verse has, not undeservedly, been taken out of the whole of scripture for this purpose. It contains all the feelings that can come upon human nature; it is very rightly and properly suited for every situation and for every need that may come upon us. Indeed it contains a calling upon God against every danger, it has the humility of a good confession, the watchfulness of constant care and fear of God, it realizes the frailty of him who prays, exhibits confidence in an answer to the prayer, and trust in the Divine protection present and ever at hand. For he who ceases not to call upon his Protector is sure of His perpetual presence.
Obedience is necessary not only for monks, but for all people. Even the Lord was obedient. Proud and self-assured do not let grace reside within them, and therefore they never have internal peace, whereas the soul of the obedient easily accepts the grace of the Holy Spirit, bringing with it joy and serenity.
That prayer may be poured forth with that fervor and singleness of heart that it ought to have, these rules must always be observed. In the first place, anxiety concerning the things of the flesh must be altogether be put away; then we must not allow to enter our minds any thought or even memory of worldly cares or business. We must cut off slanderings, vain words or many words, jestings and the like. We must root out the disturbances of anger especially, and despondency, and also tear up the
evil roots of carnal lust and avarice. And so with these and similar faults done entirely away with and cut off, - things which can also be discerned by human eyes - and with such a cleansing and purifying as we have mentioned first carried out in the sincerity of simplicity and innocence, we must lay the unshakable foundations of humility strong enough to sustain a tower which shall pierce the heavens.
The more wood you pile on a fire the more heat you get, and thus it is with God - the more you think on Him the more you are fired with love and fervor towards Him. He who loves the Lord is always mindful of Him, and remembrance of God begets prayer.
